Trapezoid Midsegment Theorem
 · In today’s geometry lesson, we will prove the trapezoid midsegment theorem, relying on the previously proven triangle midsegment theorem. The triangle midsegment theorem states that the line connecting the midpoints of two sides of a triangle, called the midsegment, is parallel to the third side, and its length is equal to half the length of the third side.

Midsegment of a Triangle The segment that joins the midpoints of two sides of a triangle is called a midsegment of a triangle. It is parallel to the third side and its length is half as long as the third side. Theorem: If a line segment crosses the middle of one side of a triangle and is parallel to another side of the same triangle, then this line segment halves the third side.

Trapezoidal rule
The trapezoidal rule is one of a family of formulas for numerical integration called Newton–Cotes formulas, of which the midpoint rule is similar to the trapezoid rule. Simpson’s rule is another member of the same family, and in general has faster convergence than the trapezoidal rule for functions which are twice continuously differentiable, though not in all specific cases.
